Extract parameters
Usage
# S3 method for numeric
empiricalParameters(y, family = "gaussian", natural = FALSE, ...)Arguments
- y
Numeric vector containing observations from a random variable
- family
Distribution family to assume for
y- natural
Should output be in terms of the natural parameter eta?
- ...
arguments passed to
empiricalParameters()
